Cousins to the Legitmist pretender to the French throne, Paul-Henri and his sisters recieved the best education money could buy. Attending the Institut Le Rosey from age 8, Paul Henry graduated in 1977 with a baccalauréat très bien. From there, he attended ETH Zurich and Cambridge before going on to work with the European Space Agency.
After France was read on to the Stargate Program, Paul-Henri was assigned as the French liason to Area 51 before being chosen to join the First Atlantis Expedition after the Battle of Atlantis. Following the recovery of the Tria crew, he was almong those who requested to remain in the city.
During the Second Exodus, he obtained a teaching position at Yale - a university which also took in his fellow former Expedition member, Irfam Abaza. Together they were able to steal copies of the galatic maps that the SGC had commissioned the university to create using data from Prometheus and Daedalus as well several of the base materials needed to create the ATA gene therapy. He is currently wanted in the United States for espionage and grand larcony, as well as by the French goverment for treason.
Additionally, he has courted fellow Émigré Miko Kununsagi from the summer of 2006, although few other Expedition members recongized it as such. His efforts succeed in the fall of 2007, when the couple were engaged. They married on 10 December, 2007 - the third of such marries among the Émigrés.
- Speaks 4 languages: French, Spanish, English, and German.
- His mother, María de las Mercedes de Borbón y Molina, was an illegitimate son of Infante Jaime, Duke of Segovia, in the Legitimist line of succession to the French throne. However, because of both his legitamcy and his female-line decent, he himself is bared from succession. Through her, he is also a great-great-great grandson of Queen Victoria, through her granddaughter Victoria Eugenie of Battenburg's marriage to Alphonso XIII. Through her, he is the first cousin three times removed of the last Russian Empress, Alexandra Feodrovna; and third cousin once removed from each Harald V of Norway, Carl XVI of Sweden, Margrethe II of Denmark, and Elizabeth II.
